I and my brother see three fireballs in sky these balls in one line one after another. I don't know that they are different- different UFO or a single UFO because they move with same speed and but with high speed after 5 sec this go away from us.

It does not make any sound.

After 20-25 min we see another thing with different shape.

I am science student i do not see such thing in my life. It cannot be any miltary vehicle.

I am not too good to detect colors but that thing has yellowesh parrot colour.
